Updated 1.15.0 release notes

Charles R Harris
Hi All,

There is a PR for the updated NumPy 1.15.0 release notes . I would appreciate it if all those involved in the thatn release would have a look and fix incorrect or missing notes.

Cheers,

Chuck

Re: Updated 1.15.0 release notes

Hi Chuck,

Are you planning on doing an rc release this time? I think the NumPy 1.14 release was unusually bumpy and part of that was the lack of an rc. One example: importing h5py caused a warning under numpy 1.14 and an h5py release didn’t come out with a workaround or fix for a couple months. There was also an issue with array printing that caused problems in yt (although both yt and NumPy quickly did bugfix releases that fixed that).

I guess 1.14 was particularly noisy, but still I’d really appreciate having a prerelease version to test against and some time to report issues with the prerelease so numpy and other projects can implement workarounds as needed without doing a release that might potentially break real users who happen to install right after numpy 1.x.0 comes out.

Best,
Nathan Goldbaum

Request for a -rc seconded (although this time we should be fine for astropy, as things are working well with -dev).

There was a 1.14.0rc1. I was too quick for the full release, just waited three weeks, so maybe four this time. Too few people actually test the candidates and give feedback, so I tend to regard the *.*.0 releases as the true rc :)

OK I guess I missed that announcement.

I wouldn’t mind more than one email with a reminder to test.

Re: Updated 1.15.0 release notes

Hi Nathan,

One very helpful think you could do, is add a Travis-CI matrix entry
where you are testing against the latest numpy nightly builds.

I got a bit lost in your tox setup, but the basic idea is that, for
one test entry, you add the following flags to pip:

-f https://7933911d6844c6c53a7d-47bd50c35cd79bd838daf386af554a83.ssl.cf2.rackcdn.com
--pre

In that case, you'll pull in the latest nightly build of Numpy.  See
the Scipy .travis.yml setup for an example.

Cheers,

Matthew

Re: Updated 1.15.0 release notes

Marten van Kerkwijk
Indeed, we do something similar in astropy, with a pre-release failure being considered breakage (rather than ignorable as for -dev):
